Getting Its Kicks: A VLBA Parallax for the Hyperfast Pulsar B1508+55
S. Chatterjee, W. H. T. Vlemmings, W. F. Brisken +7
The highest velocity neutron stars establish stringent constraints on natal kicks, asymmetries in supernova core collapse, and the evolution of close binary systems. Here we presen…
Pulsar Astrometry at the Microarcsecond Level
W. H. T. Vlemmings, S. Chatterjee, W. F. Brisken +12
Determination of pulsar parallaxes and proper motions addresses fundamental astrophysical questions. We have recently finished a VLBI astrometry project to determine the proper mot…
Pulsar Parallaxes at 5 GHz with the Very Long Baseline Array
S. Chatterjee, J. M. Cordes, W. H. T. Vlemmings +3
We present the first pulsar parallaxes measured with phase-referenced pulsar VLBI observations at 5 GHz. Due to the steep spectra of pulsars, previous astrometric measurements have…
NE2001. II. Using Radio Propagation Data to Construct a Model for the Galactic Distribution of Free Electrons
J. M. Cordes, T. J. W. Lazio
In Paper I we present a new model for the Galactic distribution of free electrons. In this paper we describe the input data and methodology for determining the structure and parame…
Far-Infrared ISO Limits on Dust Disks around Millisecond Pulsars
T. J. W. Lazio, J. Fischer, R. S. Foster
We report 60 and 90 micron observations of 7 millisecond pulsars with the ISOPHOT instrument and describe our analysis procedures. No pulsars were detected, and typical (3σ) upper…
Discovery of a New Filamentary Structure near the Galactic Center: G358.85+0.47 - The Pelican
K. R. Anantharamaiah, C. C. Lang, N. E. Kassim +2
We report the discovery of a new filamentary structure, G358.85+0.47, consisting of at least three mutually parallel but bent `strands', located about 1.5 degrees SW of the Sgr A c…
